Front

What is DNA?

Back

DNA (Deoxyribonucleic Acid) is a complex molecule that carries genetic information defining an organism's traits. It is stored in the nucleus of cells.

Front

What are the four bases of DNA?

Back

The four bases of DNA are Adenine (A), Thymine (T), Cytosine (C), and Guanine (G).

Front

What base does Adenine pair with in DNA?

Back

Adenine pairs with Thymine (A-T) in DNA.

Front

What base does Guanine pair with in DNA?

Back

Guanine pairs with Cytosine (G-C) in DNA.

Front

Which is larger: a strand of DNA or a gene?

Back

A strand of DNA is larger than a gene.

Front

Where is DNA stored in a cell?

Back

DNA is stored in the nucleus of a cell.

Front

What is the shape of the DNA molecule?

Back

The shape of the DNA molecule is a double helix.

Front

What is a gene?

Back

A gene is a segment of DNA that contains the instructions for making a specific protein or set of proteins.

Front

What is the function of DNA?

Back

The function of DNA is to store and transmit genetic information that determines the traits of an organism.

Front

What is the process of DNA replication?

Back

DNA replication is the process by which a cell makes an identical copy of its DNA before cell division.
